Chemical Description

  • Sodium Lauryl Sulfate (SLS) Powder, also known as Sodium Dodecyl Sulfate (SDS), is an anionic surfactant known for its effective emulsifying, foaming, and cleansing properties. It appears as a white or light yellow powder, highly soluble in water and capable of creating a rich lather.
  • SLS is prominently used in the personal care industry, forming a fundamental ingredient in a wide range of products such as shampoos, toothpastes, body washes, soaps, and facial cleansers. Its excellent foaming capacity enhances the cleaning and emulsifying actions of these products.
  • In the home care sector, SLS finds application in detergents, dishwashing liquids, and cleaners, where it helps in the removal of oil and dirt from surfaces and fabrics, offering a deep cleaning effect.
  • It is used as a raw material of detergent, leveling agent in printing and dyeing industry, mineral flotation agent.
  • The compound also serves a role in the pharmaceutical industry, being utilized as an emulsifier in drug formulations, aiding in the dissolution and absorption of active pharmaceutical ingredients.
  • SLS is employed in industrial and institutional cleaning agents, providing efficient degreasing and wetting properties that are essential for maintaining cleanliness and hygiene in facilities.
  • In the agrochemical industry, Sodium Lauryl Sulfate is used as an additive in pesticides and herbicides, improving the spreading and wetting characteristics of these formulations on plant surfaces.
  • The versatility of SLS extends to its use as a laboratory reagent in molecular biology, particularly in the denaturation of proteins during the polyacrylamide gel electrophoresis (PAGE) process for the analysis of protein samples.
  • Despite its widespread use, SLS is known for its mild irritation potential, which has led to the development of SLS-free or reduced SLS formulations in products intended for sensitive skin or eco-friendly claims.
  • Sodium Lauryl Sulfate's effectiveness as a surfactant, along with its cost-efficiency, continues to make it a valuable ingredient across various industries, contributing significantly to the formulation of effective and reliable products.
